Summary:

In this book, the authors present topical research in the study of the properties, health effects and environmental issues relating to phosphorus. Topics discussed in this compilation include aminophosphonate synthesis and applications; the effect of phosphorus doping on the electrical properties of diamond and carbon nanotubes; limiting nutrient and eutrophication in aquatic systems and the nitrogen/phosphorus dilemma; the environmental response of sedimentary phosphorus of shallow lakes and the anthropogenic impact; and the phosphorus complex of porphyrin.
